blue to dark

Now I am looking back what I saw in this summer.   Here is my Chicago trip in August.  Observing the change on the sky is my routin to drive back from Chicago to Iowa City.  It is alway good timing to see the sun set on Highway 88; driving from east to west toward Iowa.

This is still the blue sky but will be changing soon.

The sunset has started.

interesting clouds!

dog or bear shaped clouds kissing each other?

Now we are in dark at night.
